This error indicates that the system date is set to a date that is before MATLAB was installed. Your computer may be set to a previous date. The system date must be later than the date that MATLAB was installed.
**If the error message does not appear as obvious, the following may be seen in the lmdebug output on Linux installations:
18:09:14 (MLM) Feature MATLAB is not enabled yet
18:09:14 (MLM) Feature Distrib_Computing_Toolbox is not enabled yet
18:09:14 (MLM) License server system started on matlabr2022b
18:09:14 (MLM) No features to serve, exiting
Make sure that the system date is correct, including the Time Zone. If possible, try having your Operating System set the system date automatically. Below are directions to change the date and time on your computer based on your Operating System.
Windows
  1. Click on the Start menu
  2. Search for the Control Panel with your keyboard and then open the program
  3. Choose "Change date, time, or number formats" under Clock and Region
Linux
There are two clocks to set. Set the system clock first using the "date" command. For example to set the date to Monday, September 16th, 3:40 PM, 2022, you would type:
date 091615402022
NOTE: The system clock is set in 24 hour time.
Next you can easily set the hardware clock by typing;
hwclock --systohc
This sets the system clock time to the hardware clock.
Mac OS X
  1. Go the Applications and then open the System Preferences app
  2. Select "Date & Time"
